Nadal's actual racquet shown and his specs!

It's about 338g strung, gripped, with impact absorber 2-3g+ added, a bal. pt. of 33, no silicone in butt. NOt the advertised version of cortex, etc. at all. It's stiffer, more powerful, and as you can see in the pic, no cortex, put a paint job. He places two strips about 4" of 33mm lead tape under the grommet at 12 oclock. He uses the 1.35mm string. He strings about 54/52 and strings more frames per tourny than any other male pro. He burns through the rpm blast (used to be duralast). Mass is too light, more for a junior set up. Ra is about the same as Feds: 65. Moment of inertia is lower than Feds or Joker, who is higher than the other two.

I was religious about being at 59, but then I had one racquet at below 50 with Lux Ace. I couldn't get enough of it. Then I bought a used Prestige Pro at 53. It's just a different world. I now would string at 55.

Ah, anywhere between 40-56 is spin oriented. Depends how hard you hit through the ball also. I tend to like 57 to 58 and break the string in for an hour. Then it is at the tension I like it for the rest of its lifespan.

That makes sense If Rafa was using the out of the box Aeropro Drive I am sure he would have tennis elbow. Unfortunately most players think he is using the actual Aeropro Drive which is a lot stiffer than what he actually uses.

Yeah it is said that Rafa is using the original APD which is at a lower flex rating. With the additional weight, it makes sense he is doing more work on a flexy and heavier frame from stock (light and stiff). Djokovic's racquet is also exceptionally heavier than Rafa's and flex at around 50 RA it is rumored.
